p18570r14 tires vs p18565r14 one

currently on my camry tires size is p18570r14, will

p185r65r14 fit ?

I don't see why not, but the the speedo may be off but not by a considerable amount. To help in the future..The first number in tire size means how wide the tread is in millimeters, the second indicates how tall the sidewall is compared to the tread width in %, and the third is of course rim size. So your new size choice will only be 5% shorter than the one's currently on it. Some sizes may have LT after them, this means they are light truck tires. M+S means mud and snow, not mileage and speed(As some people think).

some one try to sell me rocky mountain tires, how good are they ?

There is a calculator on-line someplace. You'll have to google it in I am sure there are several. Generally P,LT,RT,ST are at the begining of the tire size.
